Effect of Erythropoietin on Short-term Prognosis of Newborns with Hypoxic-Ischemic Encephalopathy: A Clinical Trial
Hypoxic-ischemic encephalopathy (HIE) is a leading cause of mortality and morbidity in neonates. Head cooling is considered the standard treatment that reduces mortality and morbidity by decreasing the adverse effects of the disease. Some medicines having neuroprotective properties may be beneficial in treating HIE.
We aimed to evaluate the effect of erythropoietin (EPO) on short-time outcomes in newborns with HIE.
This study was conducted on 62 newborns with moderate to severe HIE hospitalized in Fatemieh Hospital, affiliated with Hamadan University of Medical Sciences, Hamadan, Iran, from 2019 to 2020. Eighteen patients who received head cooling plus 1000 IU/kg/d EPO were considered the intervention group and compared with 44 neonates who received only head cooling alone. Short-term outcomes, including length of stay (LOS), thrombocytopenia, seizure, need for mechanical ventilation, multiple anticonvulsant drugs, and in-hospital mortality, were compared between the groups using SPSS version 22.
The mean LOS was 21.2 ± 9.6 and 21.5 ± 12.3 days (P = 0.927), thrombocytopenia occurred in 27.8% and 34.1% (P = 0.629), and 84.1% - 88.9% of newborns required mechanical ventilation (P = 1.0). The seizure was observed in 93.2 -94.4% of newborns (P = 0.29), and multiple anti-seizure drugs were required in 35.3% and 48.9% of EPO and control groups retrospectively (P = 0.66). The mortality rate was significantly different between the EPO and control groups (11.1% vs 44%; P = 0.02).
High-dose EPO can reduce the mortality rate of neonates with HIE when used in addition to head cooling compared to head cooling alone.
